I installed the W/D combo a year ago , a lot depends on your floor plan.
I had to , go through the bed room ; fire escape ; because the door to the kitchen was too narrow.
NOTE: If you have to open the escape; the window will drop out of it's hinge, if you swing it all the way to the top. be prepared.
After getting the washer inside, there wasn't any room for a helper in the bathroom with me and the washer and it was a little awkward.
